The study area stretched from Hayling Island in Hampshire to Beachy Head in East Sussex. The environmental conditions in this area resemble the conditions that prevail in most of the aggregate dredging areas on the British south coast.

In addition to the surveys undertaken in the Year I and Year II campaigns of the project, a number of designated historic wreck sites, protected under the Protection of Wrecks Act 1973 were surveyed with multibeam sonar, magnetometer and sub bottom profiler as a project variation.
